In the delicate process, drugged rhinos are suspended by their ankles and airlifted to awaiting vehicles that will take the animals to their new home.

“It’s actually the kindest way we’ve yet discovered of moving a rhino from the field to a vehicle,” explains WWF’s project leader Dr. Jaques Flamand in a video created by the WWF’s Black Rhino Range Expansion Project.

The project, which started in 2003, aims to boost the growth rate of black rhinos in the South African area.

In the latest rescue mission, 19 black rhinos were transported by helicopter from South Africa’s Eastern Cape to new habitat in the Limpopo province.
